Make sure you're following the instructions in the "sticky guide" at the top of this forum. ProBook 4x40s owners need to use boot flags to get the installer to run.

thank you very much ... If you could get more help.... I installed Mac OS X 10.8.3 with this usb disk bootable on a 4530s model and had no problems during the installation process ....
I attach a picture if you look carefully you can see that the apple logo can be seen on a small stop sign،And then the install screen does not show turn off the laptop and should be
How can I solve this problem?
I've used unibeast 1.5.3 for create the Mac bootable disk
With Newer versions I tried but did not succeed ، And gives an error

For 4540s, you should install 10.8.4. Download fresh from Apple's Mac App Store. Use latest Unibeast to create a new USB installer. Read and follow the sticky guide carefully.

4540s is different from 4530s in that 4530s does not require boot flags to make the installer run, whereas 4540s does. See the sticky guide for instructions.
